Schneider TM2DRA8RT I/O expansion module, Modicon M238 logic controller :

The TM2DRA8RT is a digital relay output expansion module from Schneider Electric, designed for the Modicon M238 logic controller family. It provides 8 normally open (NO) relay outputs, enabling control of high-voltage or high-current devices in industrial automation systems. The module supports both AC (230V) and DC (30V) relay voltages, with a nominal operating voltage of 24V DC. Its compact design (27.3mm width × 90mm height × 84.6mm depth) and 35mm DIN rail mounting make it suitable for space-constrained control cabinets. The removable screw terminal block simplifies wiring, while built-in isolation (2300V AC rms between channels and internal logic) enhances electrical safety.
